What Crosman pellets can do--and it isn't pretty!

Here are a couple of photos that illustrate how specks of lead can embed themselves onto steel. For those of you who use or have used Crosman pellets before, you know how dirty they are. As illustrated in the pictures, the smeared lead--caused by the constant opening and closing cycle of the compression chamber of my TX200 while bearing down on the lead particles against the steel surface--is impossible to remove even when using a bronze brush and lead remover, unless a significant amount of pressure is used. Nylon bristles will not work at all! 

Anyway, I'll just let the pictures do the explaining and leave you to connect the dots that will lead you into making the conclusion as to what happens inside your airgun barrel when using these pellets. Wink-wink!

YUP! this about confirms it for me. I just posted on this as a speculation because my LGV was shooting like ass all of a sudden. Guess what? I had picked up some Brown Box Crosmans, cleaned barrel, back to almost hole in hole, shot the Crosmans again, Flyer city, cleaned again. Back on center. Stopped using them, no more problems for that session. 
 
Yes, the lead was smeared onto the steel, but it was VERY difficult to remove using just patches and a cleaning agent such as Hoppe's bore cleaner. I had to scrub the lead off with a Scotch Brite scouring pad as well. 

The purpose of the photos was to give people an idea as to what can happen to the bore when especially using pellets like those from Crosman---if that is what can happen, as shown in the photos, imagine what the bore can look like also? I just wanted to give some perspective to shooters who may be struggling to figure out one cause of accuracy from their rifle when shooting lead pellets (in general), not just Crosman pellets.

Cheers!
 
I've been washing all my pellets. Since discovering that my Pro Sport shoots the Crosman 14.3 the best between them and the JSB 15.89 and 18.1, I've used them exclusively up to now. Not seeing any lead smearing. But then, the Pro Sport chamber is open to the bottom in that area.

Still, the only way I can see particles building up in that area is if one is using unwashed pellets and as you're loading each one into the barrel, you're handling of the pellet during that operation is dislodging particles on the pellet and they fall into the compression tube chamber. Then the action of cocking the gun and movement of the compression tube back and forth, the delrin bearing smears them.

Not saying Crosman pellets aren't dirty with lead particles, as they definitely are, as evidenced by what's left in plate after I wash them. Seems like any make pellet would be susceptible to need washing.
